Note that C2x no longer had old-style function definitions and treats () in a function definition the same as (void) (in a declaration that's not a definition it still gives a non-prototype type). So with -std=c2x or -std=gnu2x, GCC -Wold-style-definition won't warn about (). -- Joseph S. Myers [email protected]
